SAN DIEGO, April 01, 2021 (GLOBE NEWSWIRE) — Diazyme Laboratories, Inc. announced March 30th that it has obtained CE-IVD marking for its SARS-CoV-2 neutralizing antibody test. The Diazyme test is a high throughput chemiluminescent immunoassay with excellent correlation to a fluorescence based neutralization assay, which has been used to evaluate the adaptive immune response in vaccine studies1. Diazyme also announced plans to work with US FDA for EUA application.
“Unlike the widely available total SARS-CoV-2 IgG antibody tests, Diazyme’s neutralizing antibody test measures the subset of neutralizing antibodies that block the interaction between the receptor binding domain (RBD) of the viral spike glycoprotein and the human ACE2 cell surface receptor. The Diazyme neutralizing antibody test gives the scientific community and health authorities a valuable tool to evaluate the level of effective antibodies generated after infection or vaccination, and to assess adaptive immunity in studies going forward. Diazyme serology tests meet real world expectations from healthcare professionals and have been independently evaluated in several published studies2–4,” said Dr. Chong Yuan, Managing Director of Diazyme Laboratories, Inc.
Diazyme Laboratories, Inc., a Life Science Affiliate of General Atomics, is located in Poway, California, USA. Diazyme uses its proprietary enzyme and immunoassay technologies to develop diagnostic test reagents run on automated chemistry analyzers and chemiluminescence instruments in user-friendly formats. Diazyme is a cGMP and ISO 13485 certified medical device manufacturer. Information regarding Diazyme’s technology and products can be found on its website at www.diazyme.com
